Гнучка кулачкова муфта NM 168

NM 168 carries 59.5 Kg*m normal torque and 125 Kg*m maximum torque in the supplied table, with a 4,000 rpm maximum reference speed. The listed bore range is 28-75 mm, outside diameter 168 mm, distance L 88 mm and approximate weight 19.30 kg. This size should be treated as a complete drive-interface review rather than a simple bore match.

• High-load reference normal torque 59.5 Kg*m
• Listed bore ceiling 75 mm
• Approximate mass 19.30 kg
• Alignment quality is a reliability input
• Describe shock/jam events in the RFQ

High-Load Interface

The NM 168 figures are kept for model matching. Larger-frame decisions should also include transient load, shaft geometry, alignment quality and handling constraints.

Flexible Center Member

The reference architecture remains a forged-iron hub pair separated by a flexible jaw element. At NM 168 scale, shaft reactions created by poor alignment can become an important reliability concern even when the coupling itself appears robust. The flexible element is not a substitute for correcting machine geometry, and its exact compound still needs confirmation for the actual temperature and media exposure.

Load And Alignment

For NM 168, combine torque, rpm, shaft dimensions and alignment quality in the same review. A 75 mm bore may fit the reference window, but the shaft key and hub section still need engineering approval. Likewise, the 125 Kg*m maximum figure should not be treated as continuous capacity. Describe starts, stops, process shocks and any expected overload so the normal operating basis can be separated from occasional peaks.

Heavy-Hub Installation

Use appropriate handling for the roughly 19.30 kg reference assembly and keep the hubs supported during positioning. Check shaft shoulders, keys and fits before moving heavy components into place. Align the driver and driven equipment accurately, verify the specified space S and rotate the system by hand when practical. Maintenance should watch for progressive element wear, fretting at the shaft fit and vibration trends.

Duty Profile

NM 168 can be considered for substantial industrial drives only after the actual load profile is known. Pumps, compressors, process machinery and other equipment may present different shock and alignment behavior even at similar power. Send operating cycles, speed, motor data and driven-machine description. If the installation is outdoors or contaminated, include environmental details for material review.

Project Machining

Project options can include finished unequal bores, keys, fit classes, identification and special finish requests. If the proposed bore approaches the upper reference value or the shaft uses an unusual key, send a drawing early. A dimensional change that affects hub strength should be reviewed before price is treated as final.

RFQ Scope

For NM 168, quotation quality improves when the buyer identifies whether the unit is a one-off replacement, approval sample or recurring production item. Include expected batch quantities and any documentation requirement so machining, inspection and packing can be planned together.
